Quantum Key Distribution (QKD) or quantum cryptography has been developed within the last decade; it is proved that QKD is secure against computer attacks and it is considered as a promising solution towards absolute security within long-term cryptosystems. Currently, research efforts are required to make strongly secure the existing communication protocols; we suggest as an issue to improve their security levels by integrating QKD. In this paper, we explore the possibility of using QKD for local area networks (LAN); we propose thus a scheme for integrating quantum cryptography in the TLS protocol. This will much contribute to enhance the process of authentication and data encryption. We present also an example to illustrate the feasibility of our scheme’s implementation.
